SPECIFICATION forming part of' Letters latent No. 638,675, datedDecember 5, 1899.

Application filed April 13, 1899.

To all whom, it 777/601/ concern:

Be it known that I, FRANK L. STEWART, a

citizen of the United States, residing at Boyne Falls, in the county ofCharlevoix and State of Michigan, have invented certain new and usefulImprovements in Feeding-Troughs for Swine, of which the following is aspecification.

The objects of my invention are, rst, to provide a trough that may bedrawn out of the reach of the swine to be filled; second, to provide forconveniently emptying refuse from the trough, and, third, to so arrangethe trough that one swine cannot interfere with another when several areeating from the same trough. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure l is a frontelevation of my device. Fig. 2 is a back elevation of the same. Fig. 3is a transverse section of the same on the line of Fig. l; and Fig. 4shows the trough and its immediate supports disconnected from the framein which it is contained and the trough tipped bottom up, as in the actof emptying refuse out of it preparatory to putting in food.

Similar letters refer to similar parts throughout the several views.

The frame A may be presumed to be a portion of the pen in which theswine are confined, a portion of a yard-fence, or other suitable supportfor the trough.

The trough O is supported in or provided with projecting ends C', thatare pivoted to the sides of the supporting-frame, as at c, so that itmay be thrown to the position indicated in Fig. 3 and rest right side upupon the supports c cin position for the swine to feed from it, or itmay be thrown over to the position indicated in Fig. 4, or bottom up,and the contents emptied from it.

The frame E is supported at one end upon the standards D, whichstandards are pivoted at one end to the frame A, as at d, and at theother end to the frame E, as at c, so that the trough may be thrown fromthe position indicated by the solid lines in Fig. 3 to the positionindicated by the dotted lines in the same figure. This is accomplishedby the use of the gate or lever B, which is pivoted to the cross-girthB', as at b', so that it may be swung Serial No. 712,943. (No model.)

over to the position indicated by its dotted lines, when the projectingedge, coming in contact with the standards D, will carry said standards,and with them the trough-frame and trough, out to the position indicatedby the dotted lines hereinbefore referred to, where the trough isentirely out of the reach of the swine and in convenient position toempty ont any refuse it may contain and to putin a new supply of foodfor the swine.

To facilitate the swinging of the trough to and from its normalposition, I place a wheel H at each side of the back end of the frame .Ein position to travel on the inclined ways I, and I aim to give theseways a proper ineline to exactly meet the elevation of the swinging ofthe standards D, so that the trough will always stand in the samerelative position, thus averting the danger of slopping the contents ofthe trough when transferring it to or from position for the swine to eatfrom.

To prevent the swine from interfering with each other when feeding, Iplace partitions, as G, just far enough apart to allow of one swinepassing his head between the partition and the end of the trough or,where there are more than two compartments, between each pair ofpartitions. Isecure one end of the partitions to the standard F and theother end to the front of the frame A. I also place a stop b" at the topof the frameA in position to stop the standards D when they are thrownout to carry the trough to position, as indicated by the dotted lines inFig. 3, to receive the food.

b represents a handle or lever with which to throw the gate B to thedesired position.

The girth G', the supporting bar or girth c', and the partitions G formguards that successfully prevent the swine from tipping the trough overor getting into it with their feet.

My object in making the lever` B b in the form of a gate is to provide asufficient weight back of the pivot-line to more than balance theportion front of this line when the lever is thrown up to position tohold the trough out, as indicated by the dotted lines in Fig. 3.

I do not wish to restrict 4myself to the use of wheels to support theback end of the trough, as other effectual means-as, for in# stance,hanging it on four standards instead IOO of two-and various otherdevices may loe applied that Will accomplish the result equally Well.

It Will be further observed that with the gate portion B of the leverextending from one standard to the other both standards must moveuniformly, and thus move both ends of the trough simultaneously.

Having thus fully described my invention, what I Claim as new, anddesire to secure by Letters Patent of the United States, is-

l. In a trough for swine, a supportingframe, a trough-frame, standardspivoted at one end to the supporting-frame and at the other end to theend of the trough-frame, Wheels at the other end of the trough-frame,and a lever to aotuate the standards to carry thetrough-frameoutandin,andatrough,sub stantially as and for the purposeset forth.

2. In Combination, a supporting-frame, a trough, standards pivoted atone end to the supporting-frame and at the other end to the trough-frameupon which the trough-frame may be swung to and from place, wheels at1one end of the trough-frame, inolines upon which said Wheels may travel,and a trough pivoted in the trough-frame so that it may be placed in theframe right side up, or may be turned over out of the frame bottom up,substantially as and for the purpose set forth.

3. In combination, a supporting-frame, a trough-frame, said trough-frameswingingly supported in said supporting-frame a trough pivoted to oneend of the trough-frame, and guards in the supporting-frame to preventthe swine from getting into the trough, subL stantially as and for thepurpose set forth.
